Title: Filtration membrane cartridge
Inventor: SHIMIZU KENJI
IPC: B01D65/00
Filed: 1993-12-08
Granted: 2000-04-25
Abstract: A pair of filtering membranes 52 are solidly bonded to a membrane-supporting plate 51 by fusibly bonding each of the filtering membranes 52 to the resin membrane-supporting plate 51. A main fusible domain 14a is formed along peripheral edges of each of the filtering membrane 52. In addition, a plurality of subordinate fusible domains 14b are intermittently formed in plural locations on one side or on both sides of the main fusible domain 14a. By virtue of the above structure, bonding strength is secured by the main fusible domain 14a, and yet, bonding strength is reinforced by locally provided subordinate fusible domains 14b. A channel is formed in the membrane-supporting plate 51 so that permeated liquid can swiftly flow through the filtering system. In addition, a plurality of projections 53 are formed an peripheral edges of a filtration membrane cartridge 5 facing inner surface of each gutter 12 formed inside of each slit plate 11 by way of causing respective projections 53 to slidably come into contact with the inner surface of the gutter 12. This in turn effectively minimizes frictional force between the filtration membrane cartridge 5 and the gutter 12 to facilitate operator to easily insert and remove the filtration membrane cartridge 5 into and from the gutter 12 of the slit plate 11.

Abstract: Un système de transmission optique comprend : un interféromètre (2) et une source de signaux optiques (24). L'interféromètre (2) comprend un coupleur optique à quatre ports (4) ayant un premier et un deuxième ports d'entrée (6 et 8) et un premier et un deuxième ports de sortie (10 et 12), une fibre optique en silice (14) raccordant le premier et le deuxième ports de sortie (10 et 12) qui présente la non-linéarité optique de Kerr, ainsi qu'un amplificateur à fibre optique dopée à l'erbium (18) situé asymétriquement entre les ports de sortie (10 et 12). La source des signaux optiques (24) est raccordée au premier port d'entrée (6) de l'interféromètre (2). Le système fonctionne selon un régime dans lequel les signaux optiques saturent l'amplificateur (18) et suppriment ainsi toute sortie oscillante, leur puissance étant suffisante pour transmettre au deuxième port d'entrée (8) un signal d'entrée couplé au premier port d'entrée (6). On obtient ainsi des caractéristiques de mise en forme et d'amplification d'impulsions qui sont relativement insensibles à la puissance d'entrée des signaux optiques provenant de la source optique (24).

Title: Process and apparatus for processing sheets of notes to form bundles of notes
Inventor: WYSSMANN HANS
IPC: B41L45/10
Filed: 1994-09-08
Granted: 2006-04-11
Abstract: A sequence of H sheets of notes, for example 100 sheets, is first of all checked for misprints, and the note positions having misprints of each sheet are stored in a computer. The sheets of this sequence then pass a numbering machine (4), which has freely programmable numbering units, which are controlled by the computer. In this case, the numbering takes place in such a way that all the satisfactory note prints within the sequence of sheets, excluding the misprints, receive a consecutive sequence of numbers, the sequence of numbers of H notes in one and the same note position being the continuation of the sequence of numbers of the H notes in a neighboring note position. The next sequence of H sheets receives the subsequent sequence of numbers. After numbering, stacks of sheets (FH) having H sheets each are formed, the stacks are cut into stacks of notes (W), and these stacks of notes are fed, ordered according to consecutive numbering, to a segregation and bundling device (9), in which the misprints are removed and in each case H successive satisfactory notes are combined to form a bundle (WB) having a complete sequence of numbers.      In each case ten bundles are packed to form a pack of notes (P).

Title: Collapsible tension-compression variable hull structure
Inventor: BULLOCK DONALD C
IPC: B63B7/02
Filed: 1995-09-12
Granted: 1998-05-05
Abstract: A collapsible tension-compression variable hull structure that collapses and stores substantially flat, yet deploys in seconds without additional parts or accessories. The tension boat design is a unique prestressed structure that strengthens the hull, reduces the need for ribs and makes the hull easily collapsible for storage and transport. Basically the present invention in it's most simple form or embodiment is a boat comprised of five simple parts: two hard, slightly flexible sides, a waterproof flexible bottom, a line running from bow to stern, and a means of applying tension to shorten the line. In the storage phase, the boat looks like two thin boards with rumpled waterproof plastic attached to the bottom. The sides bow out like an archery bow when tension is applied shortening the line. The exact beam or width of the boat depends on the amount of tension on the line. Additionally, the use of multiple tension members running through guides located off the center line of the vessel allows for most aspects of the hull shape to be trimmed and altered even while the vessel is underway. There are many optional formats for such a boat including use as a dingy, a canoe, a sailboat, or a pram, or other different variations which can be built from the same basic idea.

Abstract: An optical identification friend-or-foe (IFF) system for vehicles comprises an active cooperative identification friend-or-foe (ACTIFF) system wherein a responder optical head is located on each friendly vehicle. That responder optical head comprises a number of small panels arranged in an array with surfaces of adjacent panels being at an angle to each other, the outer surfaces of the panels being coated with laser paint designed to emit radiation at one or more selective wavelengths when subjected to a suitable interrogation pump beam. Those selective wavelengths form an identification code for a vehicle. In operation, an interrogating vehicle would transmit a narrow well-collimated infrared (IR) beam towards a target vehicle causing laser paint on the coated surfaces to emit the selective wavelengths when subjected to that IR beam.      These wavelengths can then be detected by the interrogating vehicle for identification purposes.
